        （3）This school is one of the 41 public schools in Chicago that offer Chinese classes. "In Chicago，public schools offer 12 foreign languages for students to choose.In 2018，Chinese became the second most chosen foreign language.I think it was because of the rapid development and rising of China on the world's stage." said Jane Lu，CPS （Chicago Public Schools） Chinese World language coordinator and director of the Confucius Institute（孔子學(xué)院） in Chicago.
        Steven，a sixteen-year-old junior at Walter Payton started to learn Chinese in primary school and has kept learning ever since. "（4）我選擇中文是因?yàn)槲艺J(rèn)為它將會(huì)是最有價(jià)值的語(yǔ)言。" Steven said， "More and more people speak Chinese around the world and the United States has a lot of relations with China，so I believe learning Chinese will help me in my career in the future."
        CPS started to offer Chinese as a second language choice in 1999 Only several schools had Chinese classes until 2006，when the Confucius Institute in Chicago was built.The institute is responsible for planning Chinese courses and training Chinese teachers in CPS.It also sends more than 20 CPS students to China for exchange and study every year.
